Heated Mirrors

The mirrors heat during the defrost/defog cycles for the rear window. The heated mirrors are connected to the DDM and the PDM. The DDM receives a class 2 message from the DIM commanding the heated mirrors ON. The DDM sends a SBI message to the PDM to command the passenger side mirror heater ON. The DDM supplies the voltage and current to the heater element in the driver outside mirror. The PDM supplies the voltage and current to the heater element in the passenger outside mirror.
